Find which ports program is using?h

dave13

Is there a way of finding out which ports a c++ program is using?As far as i'm concerned its only using port 80 and 8080. Reason i'm asking is cause i'm behind a college proxy and need the ports i'm using to be opened.I've got those two opened and it still doesn't work.I know it works as i've tested it at home.
Any help much appreciated.

Download FPORT.

or the rather excellent process explorer from sysinternals.com
Right-click on a process and bring up properties, then click on the TCP/IP tab to view connections/ports

i assume win XP or in that family

do do type then
start -->run-->cmd->>netstat -a or -n

will list all active connections ie open ports

#.#.#.#:portopened

like 6.32.166.8:80 ESTABLISHED

if u r on a network the list could be long so if u want to analysis it

netstat -a >>c:\mytextfile.txt
will boot out the output to the txtfile: create the txtfile first though

hope this is what ur looking for.
if u open ie or firefor and do b4 and after netstats ull see ports 80 gets opened

You only need to create the file in advance because >> is an "Append" operation. Use > instead and it will create the file for you (or, I believe, overwrite it if it already exists).

Thanks for the replies. ProcessExplorer solved my problem and gave me another in showing my program is opening ports at random. Quite a handy tool though.
